HAY-STAG K-ER.

SPECIFICATION forming part of Letters Patent No. 404,222, dated May 28, 1889. l

Application filed October 6, 1888. Serial No. 287,394. (No model.)

.To all whom, t may concern:

Be it known that I, THEoDoE H. PALM, of Sacramento, Sacramento coun ty, State of California, havcinvented an Improvement in Hay- Stackers; and I hereby declare the following to be a full, clear, and exact description ot' the same.

My invention relates to an apparatus for taking hay from a wagon or other vehicle and transferring it to a stack; and the same consists in the constructions and combinations of devices which I shall hereinafter fully describe and claim.

Figure l is a perspective view of the stack, the wagon-load of hay, and the ropes and supporting mechanism comprising my invention. Fig. 2 is a section of the clamping rollers or sections.

A A are two triangularly-arranged frames of sumcient height, which are placed at opposite ends of the space where the stack is to be formed, and are suitably guyed or braced so as to remain upright. From the apen of each of these supports is suspended a pulleyblock, B, and by means of ropes C a second block is hung from the first one, the ropes C enabling me to raise the second pulley-blocks D D to any desired point. As at present shown, the block D upon the standards at the end of the stack which is farthest from the load is considerably lower than the corresponding block upon the standard which is nearest the load.

E is a stout rope, which passes over the two blocks D D and has the end farthest from the load lirmly fixed to the ground. The other end, after passing over the pulley D', passes beneath a guide-pulley, F, and thence between the two eccentric-rollers G, the shafts of which have gearing II, which unites them together and causes them to turn in unison. These eecentrics, when turned so that the largest part of each is toward the center,will bind upon the rope E, and will thus prevent its moving, and when turned away from each other they allow the rope to move freely. A team is attached to this rope, and by its movements the motion of the fork is controlled.

I is the hay-fork, suspended by means of a pulley-block, J, from the rope E. This hayfork has the usual latch-rope, K, which is op erated by a man so situated as to load the fork at'each time when it reaches the wagon.

4The operation will then be as follows: The rope E being loosened from betweenrthe holdin g-rollers G, the weight of the fork will cause it to swing downward, and by holding the latch-rope K the two ropes K and E cause the fork to swing between the upright standards A which are nearest to the load, until it arrives at the load. The operator then fixes it so as to raise the load of hay, and the horse or team, which is attached to the outer end of the rope E, being driven out, will raise the rope E until it is drawn to a sufficient tension between the pulley-blocks D D where it will stand at an inclination, as shown in the upper dotted lines, the highest end being nearest the load. It is held at this tension by means of the eccentric-rollers G, and the teanris relieved of the strain until it is necessary to again raise the loaded fork, when the rope is released by turning` the crank upon the gear and roller shaft. By allowing the fork to travel upon this rope it will move by gravitation to any desired point over the stack, when, by means of the latch of tripping-rope K, the load may be discharged upon the stack. The lower and dotted upper lines of the drawings show two positions of the fork and traveler-rope E as the fork rises from the load.

It will be manifest that either end of the rope E may be raised so as to be higher than the opposite end, in which case the fork will then travel in an opposite direction, the change being made to correspond with the end of the stack to which the load is driven.

By this mechanism I am enabled to unload wagons at one point and buil'd a stack of any required length and height from that point without changing the setting after it is once placed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hay loader and stacker consisting of the standards and the adj ustably-suspended pulleys D D in combination with the rope E,

passing over said pulleys, having one end secured at the opposite end of the stack from the load and the other passing between the IOO holding' eccentrics or cams, so that a team may be attached the-reto, substantially as herein described.

E2. The standards having adj ustably-suspended pulleys D D', the rope E, attached and connected as shown, in combination with the fork suspended so as to travel upon the rope E, and the unloading and tripping cord, substantially as herein described.

8. A hay unloader and stacker consist-ing1 of the standards or supports with the pulleys D D suspended at diiterent heights, as described, a rope passing over said pulleys, With one end xed beyond the lowest pulley, D, and the opposite end passing beneath a guidepulley between clamping or holding' rollers and to a power mechanism or a team, by which the rope may be alternately slackened and tightened between the pulleys D D', to

gether with a fork suspended from said inzo clined rope between the pulleys, so as to travel upon it by gravitation, and a rope, K, connected with the fork, substantially as and for the purpose herein described.

In witness whereof: I have hereunto set my 2 5
